| (ii) Useful biological products can be produced by introducing portion of DNA into transgenic animals which codes for a particular product. |
| (iii) Brazzein is protein produced by a west African plant, Pentadiplandra brazzeana which is approximately 2000 times as sweet as sugar. |
| Which of the statements are given above is correct? |
A) (i), (ii) and (iii)
B) (i) and (ii)
C) (i) and (iii)
D) None of these
Correct Answer: A
Solution :
[a] (i) Transgenic animals are made to carry genes which makes them more sensitive to toxic substances than non-transgenic animals. (ii) Useful biological products can be produced by introducing into transgenic animals the portion of DNA (or genes) which codes for a particular product, e.g., human protein (a - 1 -antitrypsin) is used to treat emphysema. (iii) Brazzein is protein produced by a west African plant, Pentadiplandra brazzeana, which is approximatlely 2000 times as sweet as sugar. It is used as a low calorie sweetener. Local people have been using the super sweet berries of this plant for centuries. But the protein brazzein was patented in USA.
